REYILAI Kadeer, YUSUfUJIANG Rusuli, ADILAI Wufu, et al. MODIS data-based study of the spatial distribution of land surface temperature in Bosten lake basin area[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2017,56(5):127-138.DOI:
In order to discriminate the response of the land surface temperature (LST) to underlying surface of Bosten lake watershed area
the land surface temperatures are calculated by MODIS split window algorithm and validated using observed metrological data. The results show that:① MODIS LST product is applicable for the analysis of spatio-temporal distribution characteristics of LST in Bosten Lake watershed area. ② The distribution of land surface temperatures is very different in different seasons and different regions. The land surface temperature varies between -17.02 ℃ and 31.52 ℃ in spring
between -9.99 ℃ and 5604 ℃ in summer
between -16.45 ℃ and 37.31 ℃ in autumn
and between -32.42 ℃ and 10.79 ℃ in winter. ③ Spatial distribution of land surface temperature is related to land use types
which have affected the land surface temperature distribution in the study area. The highest LST is distributed in the desert/sandy land and the lowest LST distributed in glaciers and meadow area. The spatiotemporal distribution of LST is closely related to LUCC in the inland lake basins
and the green vegetation has the function of regulating climate and temperature in the oasis region
which is extremely vulnerable to the ecological environment of the arid region.
